The sides on our Rubbermaid litter boxes are pretty high. We do have issue with one cat scratching litter out of the front, but he manages to keep the pee in, so far For us, the litter box scatter out the front isn't such a big deal,because he doesn't do it very often. Plus, all of the other cats like to exit the boxes any way they wish, so we have litter scatter everywhere So, I end up having to sweep/vacuum every time I scoop them out. So goes life with kitties

On a side note, I find it sooo funny when I see my little CH baby, Phoebe, go potty. She always has such a look oh GREAT relief on her face, it makes me laugh
